Bokeh

Bokeh is the word of the day! If you're none the wiser Wikipedia describes it as: 

In photography, bokeh (originally /ˈboʊkɛ/, /ˈboʊkeɪ/ BOH-kay — also sometimes pronounced as /ˈboʊkə/ BOH-kə, Japanese: [boke]) is the aesthetic quality of the blur produced in the out-of-focus parts of an image produced by a lens. Bokeh has been defined as "the way the lens renders out-of-focus points of light

You can see how to imitate this effect in mixed media at The Craft Barn this week starting with my project today.
